Hi, Totally newb with PLC's. So i am sorry, if the question seems dumb. I wan't to control my 4-post autolift. In simulation, most seems fine. But the down-button does not work as i wanted it to. I have tried on-timers, off-timers, etc. It does not cut the mustard. All buttons are momentary. Ie. hold the button in to go up, down, etc. To describe the functions; Button 1 (UP): Open PV1 (Pneumatic valve1) Start the VFD in Forward Run. Button 2 "Down to safety" Open HV1 (Hydraulic Valve1) Button 3 (DOWN) Open PV1 and HV1, and run the VFD Forward control for ~1 sec., then cut the VFD, and hold the valves open. (To lift out of safety pins, and then go down.) English isn't my native language, so please ask, if theres something not clear. I have attached my file, if someone could give me a pointer, it would be nice :) EDIT: Several Youtube vidoes about LOGO! does not seem to work with my software version.. For instance, I can't get the display to show something. It would be nice to display date and time in idle, and when the UP button is pressed, then it should show "lift up" AttachmentLift control.zip (249 Downloads) |

Would this work? I have add'et some display modes.. If I4 is low, can i diaplay "Air pressure to low" or similar. Can't figure out how to couple the text to input stages. AttachmentLift_control_V3.zip (252 Downloads) |

Another suggestion from me. So I would solve it and there is only one message text requires.
